UNITED STATES PATENT OFFICE.

WILLIAM R. FOX, OF GRAND RAPIDS, MICHIGAN.

PuLLEY'-BUSH|NG.

SPECIFICATION forming part of Letters Patent No. 614,166, dated November15, 1898.

Application filed February 23, 1898.' Serial No. 671,323. (No model.)

To all whom it may concern,.-

Beit known that I, WILLIAM R. FOX, a citizen of the United States,residing at Grand Rapids, county of Kent, andState of Michigan, haveinvented certain new and useful metal or by turning down a metal tube.-

This method of making the tubular hubs is comparatively expensive, andit is therefore the object of the present invention to devise a hub orcenter which may be produced at a greatly-decreased cost.

The invention is illustrated in the accompanying drawings, in (which-Figure 1 is a side elevation of a pulley embodying my invention. Fig. 2is a sectional View of the same, and Fig. 3 is an enlarged perspectiveview of the blank from whichthe tubular center is made.

According to this invention I provide ablank A of the form shown inAFig. 3, which may be produced by rolling or in any desired manner. Thisblank comprises the thicker central portion a and the edges or iangesa', of less thickness. This blank is then bent up until the ends come incontact, as shown in Fig. 1, to form a tube, the plain face of the blankbeing on the inside, so that a tubular hub or center is provided havingshoulders to receive the cheeks and reduced ends adapted to be burredover.` The sides B B are then applied and the reduced ends of the hubburred or turned over to hold the cheeks firmly against the shoulders.l

It will be observed that the sides or cheeks are inclined at a pointWhere they abut against the shoulders and that the shoulders are correspondingly beveled or inclined, thus afford= ing a firm bearing.

From the above description the advantages of the invention will beapparent, as it pro vides a pulley which may be made complete fromsheet-steel and placed upon the market at such a reduced cost as toadmit of its being extensively used. When the hub is turned from a steeltube, however, the expense in volved in making the hub so increases the.cost of the completed article as to greatly re duce the demandtherefor.

Having thus described my invention, what I claim is:-

1. In combination, the pulley sides and the hub or bushing connectingthe same, said hub comprising the bent sheet-metal blank having abuttingends and having annular shoulders to receive the sides and annularflanges adapted to clamp the sides against the shoulders, substantiallyas described.

2. In combination, the pulley sides having central openings and flaringor inclined portions adjoining said openings, and the hub rolled from ametal blank and having inclined or beveled shoulders adapted to abutagainst the sides and ends headed over to clamp the sides in place,substantially as described.'

`In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM R. FOX.
